通過研究,得出以下主要認識: 1 、火山巖為一套以鈣堿性安山巖為主,含少量拉斑玄武巖和英安巖。On the basis of the study on the petrology, trace element, and isotopic geochemistry, the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting. one is the basanite - alkaline basalt - olivine tholeiite magma series, which are generated by partial melting from spinel iherzolite ; the other is nephelinite magma - alkaline picritic basalt magma, which are generated by partial melting of the garnet iherzolite
巖石化學、微量元素、同位素地球化學證據都表明,華北、華南地區的火山巖根據源巖和局部熔融程度的不同,可以分為兩個原生巖漿系列:一個是源巖為尖晶石二輝橄欖巖,隨著局部熔融程度的增加,形成的碧玄巖巖漿-堿性玄武巖巖漿-橄欖拉斑玄武巖巖漿;另一個是源巖為石榴石二輝橄欖巖,隨著局部熔融程度的增加形成的霞石巖巖漿-堿性苦橄玄武巖系列。From the spatiotemporal distribution of the volcanics of kalagang frn. and tiaohu fm., we can see that there are not only eruptive facies such as rhyolite but also effusion facies such as andesite, basalt and shallow intrusive rock inside the basin
從三塘湖盆地下二疊統卡拉崗組及中二疊統條湖組火山巖的時空分佈特徵可以看出,研究區既發育噴發相的流紋巖,又發育溢流相的玄武巖、安山巖及淺成侵入巖。This important tectonic zone parallel to the isotopic geochemical steep zone, which represented a suture line between the yangtze and cathaysian blocks. the geochemical evidence of the jianshui volcanic rocks from the sw part of shizong - mile zone shows that their lithologic types are tholeiites with the comparative flat ree patterns and enrichment in th, depletion slightly in nb, ta, and flat hfse. thus, they may be formed in a back - arc basin with the characteristics between morb and island - a
